Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter, and particularly to a seedling tray storage device suitable for use in a riding rice transplanter.

Generally, this type of riding rice transplanter has a spare seedling stand on which spare seedlings are placed in order to improve the efficiency of seedling planting work. When the number of seedlings decreases, a spare seedling stand can also supply new seedlings onto the seedling stand.

Normally, spare seedlings are placed on multiple seedling trays on a seedling stand, and when supplying spare seedlings, the seedlings are fed onto the seedling stand by removing each seedling tray from the seedling stand. However, in the past, empty seedling trays that had been filled with seedlings were returned to the seedling stand and stored.

For this reason, the vibrations caused by the movement of the rice transplanter, combined with the fact that the seedling tray is lighter, can cause the seedling tray to collide with various parts of the seedling stand, causing loud noise, and when driving on rough roads. In some cases, the seedling tray even fell off the seedling stand.

In addition, to prevent vibrations of the seedling tray on the seedling stand,
Proposals have been made in which the seedling tray is provided with cushion rubber or with a fall prevention device, but these have complicated the structure of the seedling tray and spare seedling stand, making them difficult to handle and increasing product costs.

Therefore, the present invention has a structure in which a hook is provided on the support frame of the spare seedling stand, and a holder is further fixed at an appropriate position below the hook, so that an empty seedling tray can be locked and stored using the hook and holder. However, it is an object of the present invention to provide a seedling tray storage device that eliminates the above-mentioned drawbacks.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

As shown in FIG. 1, the riding rice transplanter 1 has a body 5 supported by front wheels 2 and rear wheels 3. An engine 6 is mounted on the front part of the body 5, and an engine 6 is mounted in the middle of the body 5. A driver's seat 1 is provided.

Work steps 8 and 8' are provided below the driver's seat γ, and a spare seedling stand 9 is also provided at the rear of the machine body 5.

In addition, a planting device 10 is supported at the rear of the body 5 so as to be able to rise and fall freely by a link 11 and a hydraulic device. are doing.

As shown in FIGS. 2 and 11, the spare seedling stand 9 has support frames 17, 17' and a sub-frame 18 provided on both sides of the body 5, and the support frames 1γ, 11
Hooks 19, 19' are provided in the middle of '.

A holder 20.20' is provided on the side of the body 5 below the hooks 19, 19', and is configured to be able to lock and store a used empty seedling tray together with the hooks 19, 19'. ing.

At the tips of the flails 17, 17', a seedling stand 21 is provided at a slight inclination so as to descend toward the rear of the body 5, and the seedling stand 21 has a large number of partition frames 22 formed in the front and back direction. As shown in FIG. 3, the mat seedlings 23 with negative side light can be placed together with the seedlings 25.

Further, a rear frame 26 having a substantially L-shaped cross section is fixed to the rear end of the seedling stand 21 to prevent the seedlings 23 from falling downward and backward.

The appeal 126a of the frame 26, as shown in FIG.
It is bent rearward, and each partition frame 22 of the frame 26
Holes 26b and 26b' are formed near the joints with the respective parts.

Further, the seedling stand 21 is provided with a front frame 27 having a U-shaped cross section in parallel with the frame 26, and its installation position is such that the front edge 27a of the frame is located at the seedling 27 on which the mat seedlings 23 are placed. It is provided slightly forward of the center of gravity of the seedling 25 when it is mounted on the seedling stand 21, that is, shifted to the left in FIG.

As already mentioned, a large number of partition frames 22 are provided between the front frame 2T and the rear frame 26 at right angles to the frames 21 and 26. As shown in FIG. 8, between the frames 27 and 26, the lower part of the partition frame 22 bends and protrudes outward from the frame 22 to form guide rails 22a and 22a', and furthermore, the lower part of the partition frame 22 is bent toward the outside of the frame 22 to form guide rails 22a and 22a'. On the left side in FIG. 5, on the contrary, the lower part of the partition frame 22 is bent inward of the frame 22.

On the other hand, as shown in FIG. 3, the seedling 25 is provided with a hole 25a for manual operation in the front, and convex portions 25b and z5b' are formed on both sides of the tip of the seedling 25. hole 26b in rear frame 26 when seed 25 is placed on seedling stand 21.

By engaging with 26b', the seedlings 25 can be locked and fixed to the seedling stand 21.

Since the present invention has the above configuration, when carrying out rice transplanting work using the riding rice transplanter 1, in addition to placing seedlings on the seedling stand 15 shown in FIG. A large number of seedlings 25 carrying mat seedlings 23 are mounted on the seedling stand 21 of the preliminary seedling stand 9 as shown in FIG.

At this time, the seedlings 25 are placed on the guide rails 22a of the partition frame 22.

22a' onto the seedling stand 21, and the protrusions 25b and 25b' at the tips thereof are connected to the holes 26b of the rear frame 26.

26b', the seedling stand 21 is tilted backward (and the seedlings 25 are attached to the frame 26b).
, 27, the partition frame 22, etc., the seedlings are securely fixed onto the seedling stand 21.

In this state, the rice transplanter 1 sequentially plants the seedlings on the seedling tray 15 onto the rice field using the planting rod 13. However, as the rice transplanting process progresses, when the remaining bacteria on the seedling tray 15 decreases, the rice transplanter 1 1 is stopped, the seedling stand 15 is lifted upward along with the planting device 10 by a hydraulic device, etc., and the tip of the seedling stand 15 and the rear end of the seedling stand of the preliminary seedling stand 9 are moved as shown in FIG. Align them approximately.

Next, the operator steps onto step 8 or 8' shown in FIGS. 1 and 2, and holds the seedling 25 by the hole 25a for operating the seedling 25, as shown in FIG. The seedlings 25 are pulled out slightly along the guide rails 22a and 22a' to the left, that is, toward the front, and the protrusions 25b and 25b' of the seedlings 25 are disengaged from the holes 26b and 26b' of the frame 26.

At this time, by pulling out the seedling 25 toward you, the seedling 2
The center of gravity of the seedling 25 moves to the left in the figure near or in front of the front edge 27a of the front frame 2T, and the seedling 25 easily rotates up and down like a balance using the front edge 27a of the frame 2γ as a fulcrum. It becomes possible to move it.

Therefore, when the front part of the seedling 25 is rotated downward, the convex portions 25a and 25b' at the tip thereof are rotated upward, and the seedling 25 is pushed in the direction of arrow A in the figure, that is, backward.
The seedling 25 slides on the front edge 27a of the frame 27, and its tip reaches the upper end 26a of the rear frame 26.

At this time, as mentioned above, the lower front part of the frame 27 of the partition frame 22 is bent inward of the frame 2T, so it obstructs the vertical rotation of the seedlings 25 about the frame front edge 27a. Moreover, the mat seedlings 23 on the seedling tray 25 are not damaged by the partition frame 22.

In addition, since the partition frame 22 has a box-shaped structure as a whole,
It has high strength and can make the entire seedling stand 21 lightweight and compact. Furthermore, even if the seedling stand 21 for the preliminary seedlings 9 is provided in multiple stages vertically, the work of supplying preliminary seedlings in the lower level can be done by the front frame 27 and the upper level. The work can proceed smoothly without being obstructed by the partition frame 22 or the like.

By the way, when the tip of the seedling 25 reaches above the upper end 26a of the rear frame 26, the front side of the seedling 25 is lifted as shown in FIG. 10, and the seedling 25 and the upper end 26a are brought into contact with each other. The seedling 25 is tilted forward at a steep angle using the upper end 26a as a fulcrum.

Then, the mat seedlings 23 placed on the seedling tray 25 are transferred to the seedling tray 2.
5 slides downward, moves onto the seedling stand 15 that is aligned with the rear end of the seedlings, slides down the top of the seedling stand 15, connects to the rear end of the remaining germs, and forms a spare seedling. supply work will be completed.

Next, while riding on step 8 or 8', the worker holds the empty image 25, which has been supplied with preliminary seedlings, by hooks 19 and 19 of support frames 17 and 17', as shown in FIGS. 2 and 11.
19' through the hole 25a of the image subject, the image subject 2
The lower end of the image 25 is restrained from moving in the front, rear, left and right directions by holders 20, 20' provided on the fuselage 5, preventing the image 25 from getting caught in the rear wheels 3, 3, and ensuring that the image 25 is placed in a spare seedling stand. Stored on both sides.

As explained above, according to the present invention, the empty subject 25 after supplying the preliminary seedlings is the support frame 1γ of the preliminary seedling stand 9,
Hooks 19, 19' and holder 2 are attached to both sides of 11'.
0 and 20', the stored image 25 will not collide with various parts of the preliminary seedling stand 9 due to vibrations caused by the movement of the rice transplanter, causing loud noise, or if the rice transplanter is traveling on rough roads. The image subject 25 does not fall during driving or the like.

Furthermore, since the image subject 25 is locked to the hooks 19, 19' using the operation hole 25a of the image subject 25, special equipment such as cushion rubber or fall prevention device is not required. Since the structure of the image 25 and the spare seedling stand 9 can be simplified, the handling is easy and the product cost can be reduced.

Further, since the image subject 25 is stored in left and right divisions using the space on both sides of the support frame 17.degree. 11', it can be stored compactly without wasting space.

In addition, the storage work for image 25 can be done by the worker in step 8 or 8.
Since the work of supplying preliminary seedlings can be carried out continuously while riding on the rice field, there is no need to step into the muddy fields, and the worker can continue the work efficiently while remaining clean.
